Patent CA-2236176-A1 (CA)
Inventor: KLINGENSTEIN RALPH JAMES
IPC: A61J15/00
Filed: 1996-10-29
Abstract: Disclosed is an improved nasogastric tube having a coupled or integrally formed flexible tip which facilitates insertion and advancement of the tube through a nasopharynx and into a stomach of a patient while reducing the risk of trauma to the nasal cavity and perforation of the esophagus and other soft tissue. Geometry and material of the tip and tube body are selected so that the tip preferentially buckles before the tube body upon meeting body structure during advancement of the tube. Buckling of the tip passively steers the tip and tube body through the nasal cavity along the esophageal lumen, unlike conventional nasogastric tubes which tend to displace or perforate proximate body structure. Tip geometries include those which are cylindrical, frustoconical, tapered, bulbous, pleated and necked. Tips may be hollow or solid, symmetrical or asymmetrical, and may include a reinforcement member to modify the column strength thereof. One or more transition zones may be provided to transition between tube structures having differing column strengths.

Title: Egalisation de gain embouchure a recepteur dans des systemes de reception multifaisceaux
Inventor: PAPSON JOHN C
IPC: H01Q3/26
Filed: 1997-11-03
Abstract: Dans le cas de la réception de signaux par au moins deux faisceaux d'antenne en provenance du même utilisateur de système de communications cellulaires, des variations postréception du gain du canal faisceau peuvent poser des problèmes pour le choix du canal fournissant le signal utilisateur le plus fort. Le bruit atmosphérique d'origine thermique, dont on suppose qu'il pénètre de façon égale chaque faisceau, sert de niveau standard du signal pour étalonner le facteur de gain relatif de chaque canal. On mesure donc le niveau de bruit d'origine thermique au moyen d'un unique récepteur commun (32) séquentiellement couplé à chaque canal (22 - 25) de façon à écouter les niveaux de signal les plus faibles pendant les intervalles d'inactivité, et ce pendant des durées qui peuvent atteindre plusieurs heures. Les niveaux de signal les plus faibles fournissent des seuils pour chacun des canaux pour lesquels on veut établir des facteurs de correction du gain. A la réception d'un signal utilisateur sur l'un des deux canaux, on utilise ces facteurs de correction du gain pour sélectionner le canal donnant le meilleur signal, sur une base sensiblement temps réel. L'invention concerne également un algorithme de surveillance du niveau de signal le plus faible.

Patent CA-2248000-A1 (CA)
Title: Eas marker assemblies
Inventor: COLLINS WILLIAM P
IPC: G08B13/24
Filed: 1997-02-14
Abstract: An EAS marker assembly is a packaging and delivery method for large numbers of individual ferromagnetic EAS markers. The assembly is especially suited for use with an automated or semiautomated EAS marker insertion system. The EAS markers have an adhesive layer on each side to allow the markers to be attached between pages of a book. The assembly includes a plurality of markers carried by a differential release liner. The finished assembly can be in either a roll or stack form. When the roll assembly is rolled up, or when a plurality of sheets of markers are assembled in a stack, the easy release side of the differential release liner contacts one of the adhesive layers, and the tight release side of the liner contacts the adhesive layer on the other side of the marker.      When the roll assembly in unrolled, or when individual layers are separated from the stack, the easy release side of the differential release liner detaches from its adhesive layer, while the tight release side remains attached to its adhesive layer.      Thus, a layer of marker strips on top of a release liner is presented. The differential release liner allows the roll to be unrolled or the individual layers of markers to be separated from the stack while retaining the marker strips in position on the tight release side for automated pick-up and individual release of the strips by an automated insertion system.

Title: Process and plant for operating a block-type thermal power station
Inventor: HERBST MANFRED
IPC: H02J3/46
Filed: 1997-04-01
Abstract: Block-type thermal power stations generate demand-dependent useful energy, in particular current as electric energy and/or heat or cold as thermal energy. A  prospective calculation of the current and heat demand for at least the next 24h is calculated based on different presently available criteria, and the consumption integrals that may be derived therefrom are determined and evaluated. The operation of the plant, preferably in the high tariff phase, is derived therefrom with optimum evaluation of the incoming and outgoing energies. The corresponding plant contains a processor unit in an automating machine, which may in particular be a processor unit already available in the plant for which an appropriate software is created. An energy optimisation program for block-type thermal power stations is thus set up with the available data.

Title: Method for processing sugar beets to produce a purified beet juice product
Inventor: GOCULDAS BIMAL
IPC: C13B20/02
Filed: 1997-04-04
Abstract: An efficient method for manufacturing a purified juice product from sugar beets. Untreated beet juice is initially prelimed using lime and CaCO3 to produce a prelimed juice product (70). Instead of subjecting the prelimed product to main liming and dual carbonation stages, the product is delivered to a porous filtration membrane (206) which allows sugar molecules to pass therethrough whle preventing the passage of solid matter and dissolved impurities. Optimum results are achieved if the prelimed product flows across the membrane from end to end. The membrane permeate is thereafter combined with CO2(g) in a single carbonation stage to remove dissolved lime. This step generates a purified juice product (266) which can be processed to manufacture pure crystalline sugar. The membrane retentate (252) can be combined with water and refiltered to collect residual sugar materials. The foregoing process uses less energy and raw materials (e.g., lime) compared with conventional methods.
Patent CA-2254146-A1 (CA)
Inventor: HULICK TIMOTHY P
IPC: H04N5/21
Filed: 1998-11-13
Abstract: When analog and digital television signals are amplified by the same high-power amplifier in a combined analog- and digital-format television transmitter, intermodulation distortion (IMD) is caused by a digital television (DTV) signal that occupies a channel that is immediately below and adjacent an analog-format (e.g., NTSC) television signal. This cross-channel IMD must be corrected. The IMD correction may be achieved by essentially pre-correcting for radio frequency (RF) IMD by processing corresponding DTV and NTSC television signals at intermediate frequency (IF). The pre-correction is preferably achieved by tapping the DTV IF signal and using it to pre-compensate for the expected RF IMD that is inherent in the NTSC IF signal.
